Abstract: PROBLEM TO BE SOLVED: To prevent the inner part of IC from optically and electrically being observed and to prevent the reverse engineering of a semiconductor integrated circuit, by keeping a gap with wirings on insulating films and forming an opaque conductive shielding film on the same layer. SOLUTION: A polysilicon gate and the wiring 2 are formed on a silicon substrate 1, and a metallic first layer wiring 4 and a metallic second layer wiring 6 are formed on insulating films 3 and 5.

Filed: 1978-06-22
Abstract: PURPOSE:To make the device smaller in size and simpler and achieve cost reduction by providing an optical member for imaging the beam from a light source on the scanned plane to at least one of the incident window and exit window of the beam. CONSTITUTION:An imaging lens 7 for scanning is provided to the exit window of a rotary polyhedral mirror 1 and is let to serve also as exit window glass.
